Montgomery County Public Schools, Rockville, Md., is looking for an consultant to conduct a one-time review of the investment operations of its $1.7 billion defined benefit plan.

The RFP notes that as the program's investments have gotten more complex in recent years, officials would like the consultant to evaluate operations with the goal of maintaining effective oversight. "It is really a checkup on our operations," said Marisa Grant, chief investment officer of the school system's office of investments.
